library
 

in the library is ahere any way of separating video,images'audio

You can arrange the folder by file type. (View in List mode & click on the Type column bar.) This will keep them bunched into their audio, video, etc. groups. Version 5 when it's released will allow you to view video, audio, etc. that you've downlded but this will not be separate folders per se. The present beta (LW 4.9) is doing this as the image below shows. The actual physical folder however is the same as before. The advantage is that it allows you to quicky see what files of each type you've downlded via the Library window.
